So it doesn't bother you that they don't know anything because they don't sit still long enough to properly learn anything??
I've heard a story just today about someone's daughter voting for the first time on Thursday - came out from the polling station puzzled as to why there was no sign of the names Cameron Clegg or Brown on her ballot paper. I daresay she wasn't alone.
Engaged my arse.
Sounds like that particular girl wasn't switched on or engaged, but at least she cast a vote. Don't tar all youngsters with the brush of this one example. Who exactly says they don't know anything? That's your opinion. Not every teenager/young person/twenty something is like that and many can and do 'sit still long enough to properly learn'.
